OBJECTIVE: To study the etiology of macrocytic anemia in elderly patients and to evaluate the diagnostic significance of laborotory tests. METHODS: 133 elderly macrocytic anemia patients, whose age>60 years old, hemoglobin<100 g/L, mean red cell volume(MCV)>100 fL, and bone marrow cell test was performed, and these patients were grouped according to diseases, and the bilirubin, lactate dehydrogenase, folic acid, vit B12 and serum ferritin were tested, then the results of tests were compared and analyzed. RESULTS: The majority of the cases were diagnosed as megaloblastic anemia (MA), myelodysplasia syndrome (MDS), acute leukemia/multiple myeloma (AL/MM) and hemolytic anemia (HA). Usually HA was a simple anemia, while others were accompanied by decrease of other 1 or 2 series. HA patients were often with significant high level of well volume (MCV), red cell distribution width(RDW), reticulocytes (RC) and indirect bilirubin (IBIL) (P<0.01). However, MA patients were often with high level of LDH. Serum ferritin (SF) level was significantly higher in both MDS and AL/MM groups (P<0.01). CONCLUSION Common causes of macrocytic anemia in elderly patients are MA, MDS, AL/MM and HA. The combination detection of MCV, RDW, RC, LDH, IBIL and SF contributes to enhancing the accuracy of diagnosis.

Objective: To observe the clinical characteristics, treatment responses and prognosis of patients with myelodysplastic syndrome (MDS) -del (5q) syndrome who met WHO (2016) diagnostic typing criteria. Methods: A total of 77 patients with del (5q) syndrome, according to WHO (2016) classification, were retrospectively analyzed between January 2008 and April 2018 in the Blood Diseases Hospital, Chinese Academy of Medical Sciences. Clinical characteristics, lenalidomide (LEN) efficacy and survivals were compared between the patients with del (5q) alone and those with one additional cytogenetic abnormality (ACA) with the exception of monosomy 7 or del (7q) . Treatment response and overall survival (OS) were compared between patients who were treated with LEN and traditional non-LEN drugs. Results: Of 77 patients, 64 were isolated del (5q) and 13 were del (5q) with ACA. There were significant differences of the median age and percentage of patients who had small megakaryocytes in bone marrow smear by immunohistochemistry (CD41) between the patients with isolated del (5q) and the patients with del (5q) + ACA[58 (29-64) years old vs 63 (31-82) years old, z=2.164, P=0.030; and 91.7%vs 60.0%, P=0.046, respectively]. The overall hematological response rate (78.9%vs 80.0%) , complete hematological remission (CR) rate (57.9% vs 60.0%) , cytogenetic response (CyR) rate[69.2% (9/13) vs 66.7% (4/6) ] and complete cytogenetic response (CCyR) rate [61.5% (8/13) vs 33.3% (2/6) ] of LEN were similar between the patients with isolated del (5q) (n=19) and with del (5q) + ACA (n=10) , as well as the median Overall survival (OS) between these two groups of patients (62 months vs 78 months, P=0.388) . The hematological response rate (79.3% vs 36.0%) , CR rate (58.6% vs 8.0%) , CyR rate [68.4% (13/19) vs 11.1% (1/9) ] and CCyR rate [52.6% (10/19) vs 0 (0/9) ] were higher among patients treated with LEN (n=29) than those treated with non-LEN therapy (n=25) . There was no statistically significant difference in OS between the patients with LEN or non-LEN therapy (78 months vs 62 months, P=0.297) . Conclusion: Comparing del (5q) syndrome patients with isolated del (5q) or with del (5q) + ACA, two groups of patients had similar clinical characteristics, median OS and LEN efficacy. LEN showed better treatment response than traditional drugs in patients with del (5q) syndrome.

BACKGROUND: Acute alcoholic intoxication patients (AAIP) are a common public health problem. The aim of this study was to perform a comprehensive laboratory analysis for these patients to investigate the co-morbid medical problem. METHODS: We retrospectively reviewed laboratory findings of AAIP who were transferred to the emergency department (ED) from January 2017 to June 2017. RESULTS: A total of 160 male patients were enrolled. Sixteen patients (16/160, 10.0%) and three patients (3/160, 1.9%) had macrocytic anemia and microcytic anemia, respectively. A total of 33 patients (33/160, 20.6%) showed thrombocytopenia ( < 150×109/L). Twelve patients (12/159, 7.5%) showed low serum albumin level ( < 3.5 g/dL). Three patients (3/160, 1.9%) had chronic kidney disease stages 3–4 based on estimated glomerular filtration rate. Six patients (6/27, 22.2%) had high hemoglobin A1c (HbA1c) level (>7.0%). Positive rates of hepatitis B surface antigen and anti-HBs antibody (anti-HBs Ab) were 3.5% (5/141) and 49.0% (68/141), respectively. CONCLUSION: Patients with AAIP who were transferred to ED had various laboratory abnormalities (anemia, thrombocytopenia, high HbA1c). They had low positive rate of anti-HBs Ab. This might be a public health problem, suggesting the need of hepatitis B virus vaccination program for AAIP. Our data suggest the need of further nationwide studies.

Pernicious anemia is a macrocytic anemia that is caused by vitamin B12 deficiency, itself a result of the absence of intrinsic factors due to autoimmune destruction of parietal cells. We report here the case of a 43-year-old female with spontaneous remission of pernicious anemia. The patient presented with fatigue. Her serum vitamin B12 level was low, hemoglobin level was 7.6 g/dL, and serologic tests for anti-intrinsic factor and anti-parietal cell antibodies were positive. We diagnosed her with pernicious anemia, but did not administer vitamin B12 because her hemoglobin level increased spontaneously. Since then, the patient's hemoglobin and serum vitamin B12 levels have been within the normal range.

Pure red cell aplasia (PRCA) is a rare hematological disorder characterized by severe normochromic normocytic anemia and reticulocytopenia due to erythroid progenitor depletion in an otherwise normal bone marrow. Autoimmune hemolytic anemia (AIHA) is caused by autoantibodies directed against red blood cells with normocytic or macrocytic anemia with reticulocytosis. Both diseases can develop in conjunction with various underlying diseases, such as immunological disorders. Although rare, there have been a few cases of AIHA followed by PRCA. Here, we report a patient who developed PRCA following AIHA and was later diagnosed with systemic lupus erythematosus.

OBJECTIVES: To assess the current state of anemia evaluation in the elderly over 80 years of age. METHODS: Patients who were more than 80 years old and visited Dongguk University Ilsan Hospital from April 2005 to February 2014 were included. Statistical analysis were assessed using the logistic regression model. RESULTS: Total 548 patients, who had anemia according to WHO criteria, were identified. The median age was 85 years old (range, 82 to 99 years) and median hemoglobin level was 11.0 g/dL (range, 2.7 to 12.9 g/dL). Twenty-eight, 468, and 52 patients were classified as microcytic anemia, normocytic anemia, and macrocytic anemia, respectively. Among them, 397 patients (72.4%) did not undergo proper evaluation for the cause anemia i.e., 8 cases (28.5%) of microcytic anemia, 361 cases (77.1%) of normocytic anemia, and the 28 cases (53.84%) of 52 macrocytic anemia patients. The remaining 151 patients (27.6%) had completed the evaluation, and 24 patients (15.9%) were diagnosed as solid malignancies. In the assessment of iron deficiency anemia, hemoglobin levels, and age had no effect on whether or not to perform esophagogastroduodenoscopy. CONCLUSION: This finding showed that physicians often neglected anemia in individuals over 80 years of age. Though these patients have limited life expectancy, physicians should carefully discriminate the sub-population who will be benefit from adequate evaluation and treatment.

BACKGROUND: Hodgkin Lymphoma (HL) is rarely associated with autoimmune hemolytic anemia. We report here two cases of such association: Case 1: 57 years old man who presented with tiredness and pallor. Physical examination revealed multiple left cervical lymph nodes. Blood count showed regenerative macrocytic anemia with signs of hemolysis. Auto immune hemolytic anemia was confirmed by a positive direct antiglobulin test for IgG and C3d; lymph node biopsy revealed lymphocytic rich HL. Case 2: a 50 year old man being treated for HL for few months presented to the emergency room for dyspnea and pallor. Blood count showed regenerative macrocytic anemia with positive direct antiglobulin test for IgG and C3d confirming the diagnosis of AIHA as a relapse of the lymphoma. These two cases show that clinicians should be aware of such association revealing the diagnosis or the relapse of the lymphoma to distinguish it from anemia of chronic disease.

OBJECTIVETo elucidate the clinical features, response rate, prognosis and clonal evolution of aplastic anemia (AA) with macrocytic anemia (mAA).

METHODSThe clinical features at initial diagnosis and data in follow up of mAA hospitalized from January 2000 to October 2011 were analyzed retrospectively.

RESULTS(1) Of 153/568 (26.9%) cases of mAA at initial diagnosis, 114(74.5%)were non-severe AA (NSAA), 39(25.5%)severe AA (SAA) and 0 very severe AA (VSAA), while the proportion was 16.2%, 45.2%, and 38.6% in 376 normocytic anemia AA (nAA), and the difference is statistically significant(χ(2) = 181.390; P = 0.000). The median age of mAA was significantly higher than that of nAA \[30(4 - 70)years vs 19 (3 - 68) years, P = 0.001\]. (2) There were no statistical difference in hemoglobin, absolute neutrophil count (ANC), platelet count (PLT), response rate after 6 months treatment and overall survival (OS) between mAA and nAA grouped in SAA and NSAA respectively. In SAA, the reticulocyte count (Ret) of mAA was significantly higher than that of nAA \[23.90(2.99 - 61.00)×10(9)/L vs 13.1(0 - 70.60)×10(9)/L, P = 0.000\] and the proportion of erythroid cells in bone marrow of mAA was also higher \[23.5 (0 - 58) vs 14.5 (0 - 65), P = 0.043\], while they did not differ significantly in NSAA. (3) The proportion of AA with PNH clones or abnormal cytogenetics did not differ significantly in mAA and nAA groups before treatment. The incidences of AA evolved to PNH in mAA and nAA was not statistically significant (7/153 vs 9/376, χ(2) = 1.099, P = 0.294) and so was the incidence of evolution to MDS/AML(3/153 vs 13/376, χ(2) = 0.399, P = 0.528).

CONCLUSIONIn presented with macrocytic anemia at initial diagnosis of AA, higher proportion of NSAA, elderly age, higher Ret and proportion of erythroid cells are features, but being no statistical difference in the response rate, OS, and proportion of clonal evolution.
